IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent N o. 189,983, dated April 24, 1877; application led February 22, 1877.

will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication.

The nature of my invention consists in the construction and arrangement of a forcepum p, as will be hereinafter more fully set forth.

In the annexed drawing, Figure 1 is an enlarged vertical section, showing` it with one cylinder only. Fig. 2 is a detailed view of a part thereof.

The object of my invention is to produce a cheap force-pump to be used in common wells at dwellings and barns or stables in the country, or in small towns where there are no water-works; and it consists in the construction and combination of parts, as will be hereinafter more fully described, and pointed out by the claims.

VA represents the ordinary pump-stock, with tubing B of sufficient length to suit the depth ot' the well. On one or two sides ofthe stock Aare attached one or two cylinders, D D, communicating with the interior ofthe stock by passages a and b at or near the top and bottom, respectively', of the cylinders, and in these passages are placed suitable checkvalves a and b', respectively. Between the passages a and b, in the stock A, is a plug, U, forming a part of the stock A, for the purpose of cutting off the escape of the water from the tubing. On top of the stock A is an air-globe or hollow cap, E, provided on top with a lug, d, to which the handle or lever H is pivoted. The stock is thus left entire, with the exception of the hole e for the spout to be screwed in. Y

The chambers or cylinders may be made of iron or other suitable material; but I prefer to make the center of each cylinder of glass, and the heads or ends of iron, the three parts being then united by means of bolts passing through ears on the sides of the heads.

Each cylinder Discovered by a cap or head,

I, having an annular recess, with packing f to make a ltight jointwith the upper end of the cylinder. h is the piston-rod, connecting the handle H with the plunger Gr, and passing through a center hole in the head I, the lower end of the rod h attached to a bail, J, fastened to the plunger, and in the plunger is an ordinary valve t. On the under side ot' the plate or head I, around the rod h, is a recess for the reception of packing y, and on the rod his a sliding plate, P, having on its upper side a projecting hub, p, as shown.

During the operation of the pump the pressure of the water forces the plate P upward, so that the hub p will-enter the packed recess y and compress the packing therein, thusl lf'gorming an automatic or self-acting packing- This pump may be used either with one or two cylinders, as desired, and can easily be adjusted to all depths of wells.

Each rod h is preferably made iu two parts connected by a coupling-block, R. This block has a longitudinal opening for the passage of the inner ends of the two parts of the rbd h, and a transverse slot for the passage of a key or wedge, S, by which the two parts of the rod are fastened in the block, thus enabling the operator to adjust the rod h, as required.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the cylinder D, head I, with packed recessy on its under side, the piston-rod k, and the sliding plate P with projecting hub p, substantially as and for the purposes herein set forth.

2. The longitudinally and transversely slotted coupling-block It, in combination with the two parts of the rod hand the key S, substantially as and for the purposesherein set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
